I try to understand different kinds of planets as classes of astrophysical objects. I am interested in characterizing planets to better understand their composition and how they evolve with time. I am mostly a modeler and theorist and I work very closely with observers. My work involves studying the atmosphere, interior, and thermal evolution of planets at ages young and old, within the solar system and around other stars, and at distances near and far from their parent stars.
